Abstract

This paper is devoted to the study of the coupled effect between damage and elastoviscoplasticity of the 28CrMoV5-08 steel used in railway brake discs under thermomechanical loading. Isothermal and anisothermal experimental uniaxial cyclical traction-compression tests on cylindrical samples are carried out to identify the fatigue damage law and the number of cycles to fracture versus temperature. An application of the coupled constitutive equations to the stress analysis of real railway brake discs under two types of stop braking is given. The obtained cycled curves are compared with others deduced from a simple model without damage.
